 Guru Shishya Parampara, it is the cornerstone, it is the main pillar on which Sanatana Dharma stands. It is Sanatana Dharma, eternal way of living and expressing life. Why is it eternal? Because from age to age, from decade to decade, from century to century, gurus emerge, they carry on the teachings of the past, or they change. Then they bring new teachings, which are in tune with the current generations and their needs. It is an eternal, constantly in motion Dharma that evolves as time evolves. Why would anyone in their right senses reject the idea of a guru?
